Non-Production Runs and Bad Runs

Pedestal/Calibrations Updates

BeamMod Commissioning calibration runs: 6076 - 6084

Issues

  • There are some issues in the injector, resulting in large bcm asym in two runs (6086, 6087)
  • run 6087: after cut, there are still some miniruns with large injector asym in asym_bpm2i01WS, should I cut them out?
  • quite large bcm asym (324 ppm) in run 6099, don't know why. the asym in injector asym_bpm2i01WS is quite large: -8.67 compare to grand average value (< 5ppm)
  • slug 122: quite large asym. in bpm2i01WS_mean: -7.127 (usually < 5) ppm
